" Miiller described from the Cretaceous of Aix-la-Chapelle, D. 

 cidaris, D. ellipticum and D. rugosum. The last species is certainly 

 not a Dentalium, but the internal cast of a Gastrochcena (?), of which 

 the shell has not yet been observed, though the fossil is very abund- 

 ant. What Miiller understood to be D. ellipticum I cannot say, 

 nor what he identified as D. cidaris. In Miiller's collection there 

 is a piece of chert containing the impression of the anterior end of 

 a Cidaris spine with the label Dentalium cidaris Gein." (Holzapfel, 

 Palseontographica, xxxiv, p. 179).
